Technical field
The present invention relates to cooking stove technical field, more particularly to a kind of gas-cooker with aerator.
Background technology
Gas-cooker on existing market primary air major part required when burning is come injection air, because of combustion gas by combustion gas
Kinetic energy it is certain, kinetic energy declines after its injection air, causes combustion gas effectively to mix inside burner with air, affects to burn
Efficiency.
To meet the different load air ejection demand that especially high load capacity burns, at present a kind of conventional solution is
Increase an aerator on gas-cooker, the Chinese patent of such as one Application No. 201320491180.9 discloses a kind of air blast of band
The gas-cooker of machine, its air blast direction is that, perpendicular to fuel gas flow direction, and the air that Draught gas burner is blasted is from burner diffusion
Tube portion is entered, and so not only results in combustion gas kinetic energy rejection seriously, also there is the risk of gas reflux, there is potential safety hazard.
The Chinese patent of another Application No. 201310174980.2, though it can change the flowing that aerator blasts air
Direction so as to consistent with fuel gas flow direction, but it is the air blasted by increasing bigger pipeline outside burner, is changed
The original structure of gas-cooker induction tunnel is become, has not only caused furnace head structure complicated, and implemented inconvenience, quality of material has also been difficult to protect
Card.
The content of the invention
For problems of the prior art, the present invention provides a kind of simple structure, does not change the original injection of gas-cooker
System simultaneously makes blast air be sufficiently mixed, improve the gas-cooker of the thermal efficiency with combustion gas.
To reach object above, the present invention is adopted the following technical scheme that.
A kind of gas-cooker with aerator, it is characterised in that include:Burner with induction tunnel, gas distribution box, spray
Mouth, aerator, and the blast tube and blast channel being arranged on gas distribution box;The blast tube and blast channel
One end is connected with the induction tunnel mouth of pipe, and the other end of the blast tube and blast channel is connected respectively with nozzle and aerator, and
It is consistent that the blast tube flows out direction with the gas of blast air passage.
Further illustrating as such scheme, is provided with primary air injection passage on gas distribution box, it is described once
One end of air ejection passage connects with outside air, and the other end and the induction tunnel mouth of pipe of the primary air injection passage connect
Connect, and the gas of primary air injection passage flows out direction and flows out direction one with the gas of blast tube and blast air passage
Cause.
Further illustrating as such scheme, is provided with connector and blast air outlet, the company on blast channel
Interface is connected by airway with aerator, and the blast air outlet is opened for the annular for being looped around all edges of blast tube outlet
Mouthful.
Further illustrating as such scheme, the annular opening also can be replaced with annular array hole.
Further illustrating as such scheme, the gas distribution box both can integrally casting shaping or split with burner
Assembling.
Further illustrating as such scheme, the primary air injection passage is insertion gas distribution box upper and lower surface
At least two passages, each passage is evenly distributed on the surrounding of blast tube.
Further illustrating as such scheme, in the air inlet of primary air injection passage air regulating board is provided with.
Further illustrating as such scheme, is provided with for the nozzle side hole of injection primary air on nozzle.
Further illustrating as such scheme, when gas-cooker actual heating load for rated heat input, rated heat load more than 40%,
Beaten according to control signal and open automatically blower switch;Conversely, closing blower switch.
Further illustrating as such scheme, the air capacity that aerator is blasted is less than the 50% of total injection air capacity.
Compared with prior art, a kind of gas-cooker with aerator that the present invention is provided has the advantages that:
First, the feeding of blast air is realized by increasing gas distribution box at the mouth of pipe position of induction tunnel, remains combustion
The original ejection system of gas kitchen, is user-friendly to.
2nd, it is when aerator starts, air blast is empty because blast tube and the gas of blast air passage outflow direction are consistent
Direction of the gas along combustion gas into burner blasts, and strengthens air and combustion gas mixing needed for burning, reduces primary air ratio, subtracts
Few heat leakage, improves the thermal efficiency.
3rd, by arranging nozzle side hole and primary air injection passage, no matter whether aerator starts, and gas-cooker can be just
Often burning, and ensure that property indices meet relevant national standard.
4th, by being provided around blast air outlet to export the annular opening or annular array on all edges in blast tube
Hole, optimize high flame burn when combustion conditions (Huang Yan, from flame, tempering), reduce burning when flame unstability.
5th, when gas-cooker actual heating load for rated heat input, rated heat load more than 40%, beaten according to control signal and open automatically drum
Fan switch, conversely, closing blower switch;And the air capacity that aerator is blasted is entered less than the 50% of total injection air capacity
One step reducing energy consumption, improves efficiency of combustion.
